The RLS Series Single Row Deep Groove Ball Bearings represent the medium-duty tier of imperial inch-sized bearings designed to meet the requirements of machinery manufactured to British and American standard dimensions. These bearings are characterized by their robust construction and larger rolling elements compared to light-duty series allowing them to sustain higher radial and axial loads in diverse mechanical environments. Commonly found in vintage machinery, specialized power transmissions, and specific automotive components, the RLS series ensures high rotational accuracy and durability. Our inventory includes a wide range of RLS models with various sealing options such as metal shields and rubber seals to provide optimal protection against contaminants while maintaining consistent performance in demanding industrial applications where metric equivalents are not suitable.
